Abstract
The utility model discloses a waterproof cam switch, belongs to cam switches, and aims to provide a cam switch which is good in contact reliability and which has a waterproof function. The waterproof cam switch comprises a shell, an actuation mechanism, and a contact conversion mechanism, wherein the shell is composed of a cover shell (7) and a base seat (1); the actuation mechanism is composed of a rotation shaft (11) which is supported on the cover shell (7), and a handle (10) which is fixed on the rotation shaft; the contact conversion mechanism is composed of a rotator which is fixed on the rotation shaft (11), a cam (12) which is fixed on the rotator, and elastic contact sheets (13) which are fixed on the base seat (1) and located at two sides of the cam (12); a leading-out wire (5) is fixed on each elastic contact sheet (13); and a connection part of the leading-out wire (5) and the elastic contact sheet (14) is wrapped by a waterproof glue layer (2). The waterproof cam switch is reliable in contact, long in service life, and accurate in switch state.
Description
Technical field
The utility model relates to a kind of cam switch, relates in particular to a kind of water proof type cam switch.
Background technology
Cam switch mainly by being fixed on multiple cams in rotating shaft, the contact chip that lays respectively at each cam both sides forms, rotating cam can make it contact or throw off with the contact chip of both sides, thus the switching of control circuit.Current cam switch is generally Open architecture, does not therefore possess water-proof function, in a lot of particular surroundingss, can not use.Moreover, also there is the defects such as the poor reliability that easily wearing and tearing of cam, cam contact with contact chip in conventional cam switch.
Summary of the invention
For the above-mentioned defect existing in prior art, the utility model aims to provide the water proof type cam switch that a kind of contact reliability is good, have water-proof function.
To achieve these goals, the utility model by the following technical solutions: it comprises and is located at holding actuation mechanism, be located at the contact switching mechanism in this housing on housing; Described housing by case, be fixed on this case its airtight pedestal formed, described hold actuation mechanism by being bearing in the rotating shaft on case by two sealing devices, the handle being fixed in this rotating shaft forms, described contact switching mechanism by being fixed on rotor in rotating shaft, the elastic contact blade that is fixed on this epitrochanterian at least one cam, is fixed on pedestal and lays respectively at cam both sides forms; On each elastic contact blade, be fixed with respectively lead-out wire, the junction of each lead-out wire and elastic contact blade is coated by Waterproof glue line.
Described sealing device by being fixed on axle sleeve on case, the sealing ring that is embedded in this axle sleeve inner ring forms; The surface of pedestal is fixed with the lead-in wire lid that Waterproof glue line is blocked, the port of export live conductor piece of this lead-in wire lid.
Compared with the prior art, the utility model is owing to having adopted technique scheme, on the basis of traditional structure, increased the sealing device that has axle sleeve and sealing ring to form, and seal the junction between the junction to lead-out wire and elastic contact blade and pedestal and case with Waterproof glue line, therefore can effectively prevent housing water inlet; Owing to having adopted elastic contact blade, even if therefore cam occur wearing and tearing also can guarantee elastic contact blade all the time with cam good contact, not only improved cam reliability, but also extended useful life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A cutaway view in Fig. 1.
In figure: pedestal 1, Waterproof glue line 2, lead-in wire cover 3, wire pressing block 4, lead-out wire 5, rotor 6, case 7, axle sleeve 8, sealing ring 9, handle 10, rotating shaft 11, cam 12, elastic contact blade 13.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Figures 1 to 3: on housing, hold in actuation mechanism, this housing and have contact switching mechanism.Described housing by case 7, be fixed on this case its airtight pedestal 1 formed, described hold actuation mechanism by being bearing in the rotating shaft 11 on case 7, the handle 10 being fixed in this rotating shaft by bearing pin forms, described contact switching mechanism by being fixed on rotor 6 in rotating shaft 11, the elastic contact blade 13 that is fixedly embedded in these epitrochanterian two cams 12, is fixed on pedestal 1 and lays respectively at each cam 12 both sides forms; On each elastic contact blade 13, be welded with respectively lead-out wire 5, each lead-out wire 5 is coated by Waterproof glue line 2 with the junction of corresponding elastic contact blade 13.
In order to prevent into water, rotating shaft 11 is supported by two axle sleeves 8 that are separately fixed on case 7, and this axle sleeve inner ring is inlaid with sealing ring 9.In order to improve water resistance, the junction of pedestal 1 and case 7 is by Waterproof glue line 2 shutoff.
For safety, the surface of pedestal 1 is fixed with the lead-in wire lid 3 that Waterproof glue line 2 is blocked; For fear of lead-out wire 5, pulled under external force, at lead-in wire, covering 3 the port of export has and is fixed with the wire pressing block 4 that lead-out wire 5 is compressed.
Claims (3)
1. a water proof type cam switch, comprises and is located at holding actuation mechanism, be located at the contact switching mechanism in this housing on housing; It is characterized in that: described housing by case (7), be fixed on this case its airtight pedestal (1) formed, the described actuation mechanism of holding consists of the handle (10) that is bearing in rotating shaft (11) on case (7) by two sealing devices, be fixed in this rotating shaft, described contact switching mechanism by being fixed on rotor (6) in rotating shaft (11), be fixed on this epitrochanterian at least one cam (12), be fixed on pedestal (1) elastic contact blade (13) upper and that lay respectively at cam (12) both sides and form; On each elastic contact blade (13), be fixed with respectively lead-out wire (5), each lead-out wire (5) is coated by Waterproof glue line (2) with the junction of elastic contact blade (13).
